• FFmpeg Drawtext - Fontconfig error : Cannot load default config file : No such file : (null)

  29 mars 2023, par James

  I get the message : Fontconfig error : Cannot load default config file : No such file : (null).
No output is created.

  


  I have installed FFmpeg full version and written this test script to add text onto an image which I drag and drop onto the BAT file.

  


  I searched this database for solutions and found none. The script should produce an output file test.png, The image should have red text on it which reads Hello.

  


  I tried to escape the path to the Font both ways without success :

  


  `set "FONT='c\:\\windows\\fonts\\arial.ttf'" :: Font


  


  `

  


  .. and

  


  `set "FONT='c\:\/windows\/fonts\/arial.ttf'" :: Font`


  


  My full script :

  


  `set "FONT='c\:\/windows\/fonts\/arial.ttf'" :: Font
set "TEXT=Hello" :: Text (no space characters allowed, see next example)
set "COLOR=red" :: Text color
set "SIZE=20" :: Font size
set "POS_X=(w-tw)/2" :: X position of text, use (w-tw)/2 for centering
set "POS_Y=(h-th)/2" :: Y position of text, use (h-th)/2 for centering


ffmpeg -i %1 -vf     drawtext='fontfile=%FONT%:text=%TEXT%:fontcolor=%COLOR%:fontsize=%SIZE%:x=%POS_X%:y=%POS_Y%' -  frames 1 -y test.png


pause`


  


  The complete result :

"FONT='c :/windows/fonts/arial.ttf'" : : Font

• Discord Voice Bot cannot play the audio file

  7 avril 2023, par Jakub Nawrocki

  I tried to write a bot that will join the voice channel and play a audio at 20:00.

  


  Currently the bot joins the channel, but immediately after that it disconnects without making a single sound with this message :

        print(f"Audio file loaded: {source}")
        voice_client.play(source)
        while voice_client.is_playing():
            await asyncio.sleep(1)
    except Exception as e:
        print(f"Audio could not be played: {e}")

@client.event

    print('Bot is ready')
    now = datetime.datetime.now()
    target_time = datetime.time(hour=20, minute=00)
    if now.time() >= target_time:
        print(f"Current time: {now.time()}. Bot did not join channel.")
        return
    else:
        print(f"Current time: {now.time()}. Bot has joined at {target_time}.")
        await asyncio.sleep((datetime.datetime.combine(datetime.date.today(), target_time) - now).total_seconds())
        channel = client.get_channel(CHANNEL_ID)
        if channel is not None:
            try:
                voice_client = await channel.connect()
                print(f'{client.user} joined voice chat.')
                await asyncio.sleep(1)

                await voice_client.disconnect()
                print(f'{client.user} left voice chat.')
            except Exception as e:

                print(f"Error during joining channel : {e}")
        else:
            print(f"Did not find a channel of ID {CHANNEL_ID}.")

client.run(TOKEN)


  


  Any ideas ?

• Why is audio bitrate value of ffprobe output higher ?

  9 mars 2023, par 19xlr95

  When I check audio bitrate of my video via OS file details, media players or ffprobe -i my_video.mp4, I get the bitrate is 128 kbps. And I want to get more detailed meta information of the video by ffprobe -loglevel 0 -print_format json -show_format -show_streams my_video.mp4. However audio bitrate value of the output is 128615 bps.

  


  I thought it should be 128000 not 128615. Or 128 x 1024 = 131072. I wonder why it is not one of the values that I assumed. Also how can I safely say that this 128615 bps is 128 kbps ?

  


  Below is the detailed meta information for my video.

  I checked 1 kbps is 1000 bps and assumed 128 kbps of the audio bitrate should be 128000 bps. But it is 128615 bps when I run ffprobe.
